CVE-2026-105076

Executive Summary

CVE-2026-105076 is a Blind SQL Injection vulnerability (CWE-89) affecting the Appsbd Vitepos plugin (vitepos-lite) for WordPress, in versions up to and including 3.6.1. The flaw is exploitable remotely over the network by an authenticated user with high privileges (e.g., administrative or equivalent role), allowing an attacker to inject arbitrary SQL into backend database queries and infer data via boolean or time-based responses. Successful exploitation can lead to the extraction of sensitive information from the WordPress database, including user credentials, customer data, and other confidential records, potentially enabling further compromise of the affected site.

Technical Analysis

The vulnerability resides in the Vitepos plugin for WordPress. The NVD description identifies it as an "Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')" that specifically manifests as a Blind SQL Injection. The CVSS vector (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:L) indicates that the attack is network-accessible with low complexity, requires high privileges, needs no user interaction, and has a scope change, meaning exploitation can impact resources beyond the vulnerable component (e.g., the underlying database server and other applications sharing it). Confidentiality impact is high, integrity impact is none, and availability impact is low.

The "blind" nature of the injection means that the attacker does not receive direct query output. Instead, they must infer information by observing application behavior—such as differences in page content, response timing, or error messages—while injecting conditional SQL statements. This class of SQL injection is typically found in areas where user-supplied input is concatenated directly into SQL queries without proper parameterization or escaping. In the context of a WordPress plugin, such injection points commonly occur in AJAX handlers, REST API endpoints, or shortcode processing routines that interact with custom database tables or the WordPress core tables.

Given the available data, the exact vulnerable parameter, function, or endpoint is not specified. The only concrete technical facts are: the product is Vitepos (vitepos-lite), the affected version range is "from n/a through 3.6.1," the vulnerability class is SQL injection (specifically blind), and it requires high privileges to exploit. No further code-level details are derivable from the provided NVD description. An analyst should consult the plugin source code for version 3.6.1 to identify unsanitized input passed to $wpdb->prepare() or raw SQL queries.

The vulnerability is assigned CWE-89, which maps to the broader category of injection flaws. The lack of a patch and the absence of public exploit code suggest that, as of this report, the vulnerability may be known to a limited set of researchers or attackers. However, the high privileges required (PR:H) somewhat constrains the attack surface to authenticated users who already possess significant capabilities within the WordPress installation, such as administrators, shop managers, or custom roles with elevated permissions.

Exploitation Scenarios

No public proof-of-concept or exploit code is available. The following attack chain is inferred strictly from the vulnerability class and the CVSS metrics; no specific vulnerable functions, parameters, or endpoints are asserted because they are not present in the provided description.

1. Reconnaissance and target identification: An attacker identifies a WordPress site running the Vitepos plugin (vitepos-lite) version 3.6.1 or earlier. This can be done by inspecting publicly available plugin version information (e.g., via the readme file or static assets) or by using Shodan dorks to locate sites with http.html:"/wp-content/plugins/vitepos-lite". The attacker must also obtain valid credentials for a high-privileged account, either through prior compromise, credential stuffing, or social engineering, because the vulnerability requires high privileges (PR:H).

2. Triggering the flaw: Once authenticated with sufficient privileges, the attacker interacts with a plugin feature that constructs an SQL query using unsanitized user input. The exact feature is not disclosed, but typical candidates in similar WordPress plugins include AJAX actions, REST API endpoints, or administrative pages that accept parameters such as IDs, search terms, or filters. The attacker supplies a crafted input that alters the SQL query’s logic.

3. Payload execution (class-level): For blind SQL injection, the attacker injects conditional SQL statements. For example, they might submit a parameter value that appends a subquery which evaluates to true or false based on a database condition. By observing differences in the application’s response—such as whether a specific record is returned, whether a page loads successfully, or how long the response takes—the attacker can binary-search the database contents. Boolean-based and time-based blind techniques are both plausible given the "Blind SQL Injection" designation. The payload itself would be injected into a parameter that is not properly sanitized before being concatenated into an SQL statement.

4. Post-exploitation impact: Successful exploitation allows the attacker to read arbitrary data from the database accessible to the WordPress database user. This includes the wp_users table (usernames and password hashes), wp_usermeta (including session tokens and capabilities), and any custom tables created by the Vitepos plugin, which may contain customer orders, payment metadata, inventory details, and personally identifiable information. The high confidentiality impact (C:H) reflects the potential for large-scale data exfiltration. The scope change (S:C) indicates that the compromised database could be leveraged to affect other components, such as other applications sharing the same database server. Integrity impact is none (I:N), meaning the attacker cannot modify data through this specific flaw, and availability impact is low (A:L), suggesting minor disruption such as increased load from time-based queries.

Impact Assessment

The business impact of CVE-2026-105076 is significant for organizations running affected Vitepos installations. The vulnerability enables an authenticated high-privileged attacker to exfiltrate sensitive data from the WordPress database. In an e-commerce or retail context—which Vitepos serves as a point-of-sale and inventory management plugin—this could include customer records, order histories, payment-related metadata, and internal inventory data. Such a breach can lead to regulatory penalties (e.g., GDPR, CCPA), reputational damage, and financial loss.

The CVSS v3.1 base score is 7.6 (High), with the vector CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:L. The confidentiality impact is rated High, indicating a total loss of confidentiality of some database contents. Integrity and availability impacts are None and Low, respectively, meaning the attacker cannot alter data and only minor availability degradation is expected (e.g., resource consumption from time-based queries). The Scope metric is Changed (S:C), which means the vulnerable component (the WordPress plugin) can affect resources beyond its security scope—specifically, the underlying database server and potentially other applications hosted on the same database instance. This elevates the severity beyond what a simple data leak might suggest.

The blast radius is determined by the database user’s privileges. In a default WordPress configuration, the database user has access only to the WordPress database (all tables within it), not to other databases on the same MySQL/MariaDB server. However, if the database user has broader permissions, or if multiple applications share the same database, the scope change could allow lateral movement to other data stores. The high privilege requirement (PR:H) limits exploitation to users who already have administrative or equivalent access, reducing the likelihood of opportunistic attacks but increasing the impact when a privileged account is compromised—for example, through phishing or credential reuse.

Affected systems are any WordPress installations running Vitepos (vitepos-lite) version 3.6.1 or earlier. No specific version range beyond "through 3.6.1" is provided, so all prior versions are presumed vulnerable.

Mitigation & Patch Guidance

Patch confidence: 0/4 (UNPATCHED — no patch evidence from any tracked source). As of this report, no vendor patch or official fix is available.

1) Immediate mitigations:

• Deactivate and uninstall the Vitepos plugin if it is not business-critical. If uninstallation is not feasible, disable the plugin until a patch is released.
• Restrict access to the WordPress admin dashboard and any plugin-specific endpoints to trusted IP addresses using web server access controls or a Web Application Firewall (WAF).
• Enforce strong authentication for all high-privileged accounts, including multi-factor authentication (MFA), to reduce the likelihood of credential compromise—given that exploitation requires high privileges.
• Deploy virtual patching via a WAF with SQL injection rulesets (e.g., ModSecurity OWASP Core Rule Set) to block malicious payloads targeting the plugin.
• Monitor web server and database logs for SQL injection patterns, especially requests containing SQL keywords in parameters associated with the plugin.

2) Patch/upgrade steps:

• No patch is currently available. Monitor the official WordPress plugin repository and the vendor’s website for an update to Vitepos. When a patched version is released, upgrade immediately.
• If the plugin has been abandoned or no fix is forthcoming, consider replacing it with an actively maintained alternative that provides equivalent functionality.

3) Long-term hardening:

• Adopt a least-privilege model for WordPress user roles. Ensure that only essential personnel have high-privileged accounts, and regularly audit user capabilities.
• Implement database user segregation: the WordPress database user should have minimal privileges (SELECT, INSERT, UPDATE, DELETE on the WordPress database only) and no access to other databases or administrative functions.
• Regularly scan for vulnerable plugins and components using a software composition analysis (SCA) tool or a WordPress-specific vulnerability scanner.
• Conduct secure code reviews for any custom plugins or themes, focusing on proper use of parameterized queries and escaping functions (e.g., $wpdb->prepare()).
• Enable comprehensive logging and alerting for database queries and web requests to detect anomalous activity indicative of SQL injection attempts.
